c# datagridview与DataSet绑定， 列与数据库表里面的列一一对应

System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.Collections; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } DataTable tblDatas = new DataTable("Datas"); private void Form1_Load(object sender, EventArgs e) { DataColumn dc = null; dc = tblDatas.Columns.Add("ID", Type.GetType("System.Int32")); dc.AutoIncrement = true;//自动增加 dc.AutoIncrementSeed = 1;//起始为1 dc.AutoIncrementStep = 1;//步长为1 dc.AllowDBNull = false;// dc = tblDatas.Columns.Add("Product", Type.GetType("System.String")); dc = tblDatas.Columns.Add("Version", Type.GetType("System.String")); dc = tblDatas.Columns.Add("Description", Type.GetType("System.String")); DataRow newRow; for (int i = 0; i < 20; i++) { newRow = tblDatas.NewRow(); newRow["Product"] = "大话西游"; newRow["Version"] = "2.0"; newRow["Description"] = "我很喜欢"; tblDatas.Rows.Add(newRow); } newRow = tblDatas.NewRow(); newRow["Product"] = "梦幻西游"; newRow["Version"] = "3.0"; newRow["Description"] = "比大话更幼稚"; tblDatas.Rows.Add(newRow); dataGridView1.DataSource = tblDatas; //dataGridView1 } private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e) { //datagridview变化DataSet数据跟随变化； tblDatas.Rows[e.RowIndex][e.ColumnIndex] = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString(); } private void button1_Click(object sender, EventArgs e) { //这个是DataSet数据变化datagridview跟随变化； //这个要根据实际来的，这里只有修改dataSet中一个单元格的数据。 tblDatas.Rows[5][1] = "5555555555"; } } }

 

参考代码2

手动分别赋值方式。

DataSet ds_sp = new DataSet();
DataTable dt_sp = new DataTable();

if (string.IsNullOrEmpty(strFilter))
{
strFilter = " 1=1";
}
dt_sp = DbHelper.getSqlTaskList(tablename, "*", sortExpr, this.SGVTask.PageSize, pageIndex, 0, strFilter, sortDirect);//Sql 中使用翻页函数

DataTable dtTask = dt_sp;

for (int i = 0; i < dtTask.Rows.Count; i++)
{
DataRow dr = dt.NewRow();
dr["YMD"] = dtTask.Rows[i]["YMD"].ToString();
dr["SDSHAN"] = dtTask.Rows[i]["SDSHAN"].ToString();
dr["ABALPH"] = dtTask.Rows[i]["ABALPH"].ToString();
dr["XSJE"] = dtTask.Rows[i]["XSJE"].ToString();
dr["FenTan_Month"] = dtTask.Rows[i]["FenTan_Month"].ToString();
dr["Cont_KeBian"] = dtTask.Rows[i]["Cont_KeBian"].ToString();
dr["Contract_Num"] = dtTask.Rows[i]["Contract_Num"].ToString();
dr["FenTan_Mode"] = dtTask.Rows[i]["FenTan_Mode"].ToString();
dr["FenTan_BL_Je"] = dtTask.Rows[i]["FenTan_BL_Je"].ToString();
dr["CJ"] = dtTask.Rows[i]["CJ"].ToString();
dr["FixSmOrderNum"] = dtTask.Rows[i]["FixSmOrderNum"].ToString();
dr["ftfs"] = dtTask.Rows[i]["ftfs"].ToString();
dr["FTDAI"] = dtTask.Rows[i]["FTDAI"].ToString();
dr["DAIKM"] = dtTask.Rows[i]["DAIKM"].ToString();
dr["FTJIE"] = dtTask.Rows[i]["FTJIE"].ToString();
dr["JIEKM"] = dtTask.Rows[i]["JIEKM"].ToString();
dr["MEMO"] = dtTask.Rows[i]["MEMO"].ToString();
dt.Rows.Add(dr);
}
this.SGVTask.DataSource = dt;
this.SGVTask.DataBind();

 

参考方式3 映射方式：

先在DataGridView中定义一些列，将这些列的DataPropertyName设置为查询得到的数据库的返回的DataSet中相关DataTable的列名称。

具体的属性设置可参考本博客文章：C# DataGridView的列对象属性探讨 (未完待续)。
